A lever P secu M, engages beneath th ro rod. to. release the brake fh tuated to start. The operation is as f The engine or moto friction members continu rate of speed .which, of eo as desired and both drivin friction members obliquely with the con that the pressure etcerted by the lever M to forc ll e driven friction member against the, drivlng frlction members causes the driving I friction members by their rotation, to gradually force the driven friction members outwardly and the engine rate being uniform, accelerating the rate of the driven friction, members and the motion of the car. the car has attained sufficient rate of speed, the accelerator lever is released, permitting the driven friction members to again assume a position at right angles with the driving radiiis, of course, in retracting the driven friction members instoppingor when employing the drivenfriction members as a brake the inward movement of the driven friction members'may'be aided by reversely adjusting the accelerator lever, and by theuse of the accelerator less wear is occasioned on the friction faces than when the friction mem' bers areshifted otherwise. The accelerator also greatly relieves the labor necessary in shifting the friction members to vary speed.

Of course, ina device such as described the frictionmembers o erate as a powerful brake d enable the car to be stopped or reversed much more quickly than possible with other types of transmission mechanisms. Furthermore all the mechanisms for shifting the driven friction members and for operating-the vehicle are positioned below the floor thus carrying the center of gravity lower than usual. The ends of the tubularcasing containing a part of the shift= ing mechanism for the driven friction mem' bersafford a bracket or support for the side step R, as shown in Figs. 2 and 10, thus en ablingthe said casing to be made of suflicient length to afford greatamplitude of adjust-. ment for. the driven friction members,

. Obviously the combined reach rod and chain guard, afford a suitable connection be, tween the adjustable, transmission shaft E, v

and rear axle to insure the effective transmission to the same at all time. Obviously the friction members maybe shifted automatically. by means of the accelerator or.

mechanically by means of "a suitable hand wheel on the outer post K. Many details of construction may be varied invention. i
